Curious why it would be copyright vs patent. Weights are in essence part of an invention - I think the specific numbers would be pretty weird to copyright, but patenting the system that includes the model architecture and training process would offer a much more robust protection that's more along the lines of past physical inventions. I'd be interested to look and see if there are any old analog computer patents, and how they are worded? Like if the specify list of resistor values, or focus more on architecture and tuning. I think that's a possible precedent to look to.
